The Jonas Brothers attend a surprise event for We Day on Wednesday afternoon (February 6) in Minneapolis, Minn.

The guys — Nick, Joe and Kevin — surprised over 600 students at Minneapolis Patrick Henry High School for the launch event with Free The Children.

The event announced a concert featuring the JoBros for October this year — but students can’t buy a ticket — they have to earn it by making a commitment to service for one local and one global action as part of the year-long We Act program.

We Act is a free, year-round educational program that helps students turn the inspiration of We Day into sustained social action. The ultimate goal is to raise a generation of active global citizens.
